Did some diggin on other sites and found that this is an issue with windows. Both Laptop and TV support HDR but for some reason it just doesn't seem to work. Once "use HDR" is selected, the option to disable it disappears and can't be reversed conventionally. The only fixes so far are to:
According to Lanka - Microsoft Agent, the only option is to use system restore to an earlier point.
This was Dennis EK's solution over at MIcrosoft Community:

I had the same exact issue and solved it by undoing the HDR setting via regedit.exe. The settings are stored in the following location in the registry:
Each monitor has its own subkey (subfolder) in that location. The name of the value setting is "AdvancedColorEnabled". Set the value to 0 or remove the value, then reboot the PC. After the reboot, I enabled my external monitor again and it worked as normal."
Thankfully this worked for me, thank goodness. I changed the registry value to zero, restarted my PC and BOOOOOM. HDR was disabled and I could output video TV only and was playing games again.
Only issue now is I can only get my laptop to output a 4K@60hz(selecting 120hz auto reverts to 60hz) or 1440p@120hz signal, any Display Settings or Nvidia Control Panel adjustments auto-revert to 60hz. Is it the HDMI cable I am using or what?
